Need Release Coolant Filters (Non-Oat Systems) - Detroit Diesel Series 60 Operator's Manual

HOT COOLANT
To avoid scalding from the
expulsion of hot coolant, never
remove the cooling system
pressure cap while the engine is
at operating temperature. Wear
adequate protective clothing
(face shield, rubber gloves,
apron, and boots). Remove the
cap slowly to relieve pressure.
For best results make the test while
the coolant is between 50 – 140 F
(10.0 – 60 C). Wait at least 60, but
not longer than 75, seconds before
reading the nitrite level. Use the test
strips as follows:
1. Dip the strip into coolant for
one second. Remove and shake
briskly to eliminate excess fluid.
2. Immediately compare the pad end
(% glycol) to the color chart on
the container.
3. Sixty seconds (one minute) after
dipping, compare the nitrite pad
to the color chart.
4. Color change of the additive
indicator (middle pad) indicates
the presence of inhibitor that is
not approved by Detroit Diesel.

SERIES 60 ENGINE OPERATOR'S GUIDE
Promptly replace and tighten the test
strip container cap after each use.
Discard unused strips if they have
turned light pink or tan.
A factory coolant analysis program
is available through authorized
Detroit Diesel service outlets. Part
numbers are listed in Table 47 in the
Specifications section. To verify
coolant acceptability, submit a sample
for coolant analysis every two (2)
years, 300,000 miles (480,000 km),
or 10,000 operating hours, whichever
comes first.
Need Release Coolant Filters
(Non-OAT Systems)
Spin-on coolant filters are available for
Detroit Diesel engines. Membranes
in the filters release SCAs before
the coolant approaches a corrosive
condition, protecting the engine from
corrosion. The elements release the
SCA charge as needed, as opposed to
the maintenance SCA elements, which
instantaneously release the SCA
charge. Coolant filter elements should
be replaced after one (1) year, 120,000
miles (192,000 km) or 2,000 operating
hours, whichever comes first.
